Abstract

La présente invention concerne un dispositif et un procédé de codage d'une vidéo en 3D, et un procédé de décodage selon la présente invention comprend les étapes consistant à : décoder des informations sur un mode intra-saut pour un bloc actuel ; calculer, en tant que mode intra-saut, un mode de prédiction du bloc actuel d'après les informations sur le mode intra-saut ; générer une liste de candidats pour le mode intra-saut ; et générer un échantillon de reconstruction du bloc actuel d'après la liste de candidats. La présente invention peut réduire le volume de données devant être transmises et améliorer l'efficacité du codage en codant un bloc actuel selon un mode intra-saut durant le codage d'une vidéo 3D. La présente invention peut également exécuter une procédure intra-saut selon un mode intra-directionnel en utilisant un bloc voisin durant le codage d'une vidéo 3D, et reconstruire le bloc actuel sans signal résiduel.
